Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Datsun debuts new seven-seat Go+ in Indonesia [w/video]

The Datsun name may have long since been replaced by Nissan, but the old brand is making a comeback - in certain markets, at least. Nissan relaunched the Datsun brand in July as its new budget brand for developing markets with the debut of the Go hatchback, and has now followed up with the addition of the larger Go+.
Set to be built in Indonesia at Nissan's plant in Purwakarta, the Go+ debuts today in the capital of Jakarta as the second model in the new Datsun lineup. The seven-passenger minivan features flexible seating in a compact form 13 feet long, powered by an unspecified 1.2-liter engine mated to a five-speed manual transmission.
Nissan isn't saying much else about the model, but hopes the new Datsun twins will account for half of its sales in Indonesia within three years. The low price target for both models - set to come in at less than 100 million rupiah ($8,700) - ought to help it get there. The lineup is then scheduled to reach other markets, starting with India, Russia and South Africa next year.

Datsun reveals new On-Do budget sedan in Russia [w/video]

When Nissan revived the Datsun brand name, it essentially hit the "undo" button on the rebranding it undertook decades ago. But this time, the Datsun name is being used solely as a budget brand for developing markets. The reborn marque launched in India this past July with its Go hatchback, returned in September with the Go+ minivan and revealed the Redi-Go concept just last month. And now it's back again with the new On-Do sedan.
Launched in Moscow by CEO Carlos Ghosn, the On-Do was designed and engineered in Japan specifically for the Russian market - Nissan's fifth largest worldwide - where it will be built at the AvtoVaz plant in Togliatti. Decidedly budget-oriented, the Datsun On-Do is a four-door, five-seat econo-box measuring 172 inches long, 67 inches wide and 60 inches tall with an 18.7 cubic-foot trunk which Datsun describes as class-leading. Punctuating an otherwise bland shape is a large front grille and lighting front and rear that looks (and very well might be) bigger than the wheels.
Not that the Datsun On-Do needs a big contact patch to transfer power to the road: motivation is provided by a 1.6-liter engine with a grand total of - wait for it... wait a little longer - 87 horsepower. Which might strike you as a reasonable amount of muscle, considering the 400,000 rubles Datsun is getting for the On-Do (but consider that translates to about $11,300). That's a couple grand more than what Nissan gets for the Micra in that other giant northern country, or about the same amount it gets for the Versa in the US (which sells in Russia for 499k in rubles) - both of which are powered by what is in all likelihood the same 1.6-liter four but producing 109 hp. Of course Russia has different tax rates than the United States or Canada, but with such little power, the Datsun would fall into Russia's lowest tax bracket.
